MPFI Complete Dyno Runs - 88-91 Civic & CRX

Here's it is!! All wrapped up and running like a champ. I had a fun time finishing up the MPFI conversion on my 1991 Civic Wagon DX. I love how the car feels now and with a few more "breathing" upgrades I think it'll really open up and be a fun little machine!

[@GarageBuiltHondas]

So what do you all think of the MPFI gains!?!

[@HustlePaul]

Jon Widmer great job reminds me of my 88 ef l sedan I had. but I ran same si trans , d16y8 intake manifold and throttle body and dc header. made a good difference in power . better throttle response. but I eventually swapped in a d16a6 and converted to obd1 than sadly had to sell the car

[@joethecollector]

Jon Widmer great tutorial and I would do it! anything to improve the d15b2 is worth it.

[@mobtiesatl619]

Jon Widmer nice

[@BoostedPastime]

if your keeping your d15b2 then yes its worth it. otherwise I'd say go y7, y8, or Z6

[@boostben]

% gain is actually quite a lot.

[@tomhanson329]

This was the best series I've ever seen. I suck at wiring, I mean I am terrible but the way this was explained I really feel like I can do it my self

[@GarageBuiltHondas]

Awesome Tom, I tried to make it simple. Good luck, if you need any help let me know.

[@jemyflawfle9854]

Great swap guide , lots of valuable information makes me a lil more comfortable about doing my swap

[@GarageBuiltHondas]

Its intimidating but pretty easily done if you have the patience.

[@hond4srule]

Awesome, just finished a rear disc swap on my 91 sedan and waiting on parts for my own mpfi conversion. This series has really got me amped for the result.

[@GarageBuiltHondas]

Need any specific parts?

[@hond4srule]

The only thing I'll need as long as everything ships will be an si intake hose.

[@GarageBuiltHondas]

Alright, don't have an extra one. I'll keep an eye out from my friends, someone might have one.

[@hond4srule]

Jon Widmer Dude, what an awesome gesture! Keep up the great videos.

[@GarageBuiltHondas]

Will do man!!

[@hondahomies8915]

This is an amazing channel for any Honda fan! I dig knowing that there are others like me, 96 Accord EX Was my first car and I still have one.

[@GarageBuiltHondas]

Thank you!!

[@brittonwritespoetry]

Another cool addition to your channel Jon. I appreciate the detail and the split screen comparison you did to show us the difference in performance from the manifold swap. Awesome! It'll be interesting to see what kind of improvements the future intake and exhaust mods will bring when you dyno it again.

[@GarageBuiltHondas]

Thanks Britt!! I was so curious myself and had to do the split screen. I've done a handful of MPFI swaps and never knew what power or difference it made. Might not seem like tons but it's essentially just an intake manifold upgrade but also allows for ease of more mods, and also doing future engine swaps. The wiring is done for any obd0 b18 or b20, and to add an obd0 B16A you'll just add 3 more wires to the Ecu (knock sensor, vtec pressure switch, and vtec solenoid). So worth it if any Ef owners plan on upgrading!

[@baddestburrito]

Wow! This was SUPER interesting, and encouraging, too! I cannot believe the mileage on your car! And, to think that it still makes just as much power as it did when new, this is incredible. I doubt that any modern car -- 26 years from now -- will be able to brag the same way. Honda of the 90s, TRULY built incredibly reliable machines, that also are a riot of fun to drive. Truth be told, I feel relieved and foolish after watching this video. See, I have just a tick over 100,000 on my '91 Si. Everyone around me says that this is low, "for its age." Next to YOUR mileage, though, it has me thinking that this engine of mine is still just a baby, with lots and lots of life still left in it. It'll probably outlast *me*. (I keep on top of all maintenance, and I use only synthetic oil. I will be switching to synthetic Rotella T6 at my next oil change, so I expect to enjoy many more years of motoring.) That's the relief part of the equation. I feel foolish, when I think that I was worried about how much more life I have in this D16A6. Haha. I didn't need to worry at all, it would seem. I am learning so much about my car, thanks to you, Jon. I will continue to eat up any videos you post in the future.

[@GarageBuiltHondas]

Baddest Burrito Very awesome!! Your motor is fresh out of the box compared to mine! As long as you maintain it, and as meticulously as you are you shouldn't have any problems at all! I'm glad you're learning about your car, it'll make you love it that much more! You'll probably never sell it now! Lol

[@dailygarage5635]

don't see too many videos like this about the good Ole manifold swap, none at all to be honest. great video man once again!

[@GarageBuiltHondas]

Daily Garage thanks man, I wanted to make a detailed series on getting it converted and have it stand the test of time. I'm hoping I accomplished this!!

[@austinjohnson2162]

The best dpfi to mpfi video or write-up on the the internet bro great series!! Always enjoy your videos man. btw is there any reason your not running the traklites on your track car? I just grabbed a set of Traklite Gears 15x7 in arctic white for my ED Sedan was wandering how you like em??

[@GarageBuiltHondas]

Austin Johnson Great wheels! I just have a handful of different sets and my Gears have had an all season on them since the day I got em. My Konig Dial-ins are the same as the gears in size and weight and those are what I had been using up until I got the Buddy Club wheels. I think you'll like them, they are super nice!

[@austinjohnson2162]

Jon Widmer Oh ok that makes sense. Yea i got a set of Bridgestone Potenza RE71Rs 205-50-15 on the way as well. I guess we'll see how they handle up at the track ive only heard good things about em.

[@GarageBuiltHondas]

You'll be set with those tires on those wheels! A good Miata friend was telling me that a lot of miata guys run the Re71's because they have to stay in the 200TW category, but these perform more closer to those of a 100TW. I didn't know this but will like to try a set out once I wear out my NT01's. Let me know how they feel and how you like them once you've beaten on them! 😀

[@austinjohnson2162]

Yep guys are running under 2 min at butttonwillows cw13 with the re71rs. Im sure you already know thats a really good time. I wont be hittin the tracks till july unfortunately but I'll let you know how they handle. It will also be my first track event. Ughh cant wait till july bro Vtec Club at buttonwillow! The power of dreams. 👍🍻

[@GarageBuiltHondas]

I feel your pain, I have to wait til May 28th and it feels like freakin forever!! Take some video, get a window mount and use an app like Track Addict and record your sessions. I'd love to see it! I would love to get out there one day, it looks like such a fun track!

Great looking cars!! I fell upon your channel because of your toyota pickup lowering DIY. I am in the market to maybe buy one as a daily. But I really gotta give you props on the amazing job you do on all your cars. The attention to detail on the small things is awesome. I love these little cheap cars that will really run forever if you just give them a little attention. There is something so satisfying with making all the little things work properly and then making little subtle mods to make to make the car look so much better. Thumbs up to you!!

[@IntegraDIY]

At the end of the day, the dyno just measures peak power numbers. The 0-60 definitely got quicker and it pulls stronger with the mpfi.. merging on the freeway is less dangerous now with more pep

[@flatwoodzmafia]

I know its an old video, but im about to be doing a d16a6 swap in my hatch. All that I've got to get is a distributor and then do it all. my poor d15b2 was already low on power and it finally decided to let go. But honestly this video series helped a ton in figuring out everything that i needed. But i ended up getting an si harness too instead of extending all the wires

[@GarageBuiltHondas]

[@rt4wd_wolff]

Jon Widmer As far as content goes, you are always thorough and you cover everything correctly and your work is always really clean and looks OEM. I always cringe when I see guys cutting corners and doing hack jobs, it just gives the Honda community a bad name. I wanna see more creative shots of your cars maybe drone shots and some music! Just a thought! 👍

[@GarageBuiltHondas]

Agreed, and agreed!! I want to do more "artistic" videos of the cars too. I enjoy filming those a lot and would love the opportunity to get better at editing/filming!

Good job John,so happy it all worked out.time to get my wagovan back on the road! keep up the great work! 👍✌

[@GarageBuiltHondas]

oldskool DA9 yo, didn't know you had one also!! Get to work son!!

[@ricerocket_ed6650]

This was totally sick man! I guess that means that on a good day you're making over 100hp to the crank, my 2006 Scion xB makes an astounding 82whp! And it's heavier than your wago as well, so nice

[@GarageBuiltHondas]

Yes, probably right around there at the crank. Intake and exhaust will make a little more probably too!! Damn, I didn't realize they had such little power!

[@ricerocket_ed6650]

Haha yeah, 103 crank horsepower translates after 200k to roughly 82, a tad disappointing but behind the wheel it actually doesn't feel that bad

[@GarageBuiltHondas]

EF_Wagon I'm sure it's just a cruiser anyway, but when you actually know the hp #'s it always makes the car feel slower! Lol

[@ricerocket_ed6650]

Yeah I know what you mean. There's no mistaking her for a race car, but it does drive pretty well. I'm in the process of selling it for an EF/ED6 hatch or CRX, your channel introduced them to me and I've been madly in love with early '90s civics since, so thanks a ton for that :D I can't wait to get an EF hatch

[@GarageBuiltHondas]

Josh Elkins Good luck man, take your time and double check your work!!

[@brittonwritespoetry]

Man,Honda has so many different engine setups and variations it's crazy. They're all over the place with part numbers like PR3,PR4,PM7,PM6,P08,PLC,....I sell auto parts in Jamaica so it's been cool learning the various part numbers from different Japanese makes especially Honda. Theirs is very logical and they make it easy to get items like head gaskets,water pumps and timing belts. As I'm sure you've come across all sorts of technicalities with these. It's fascinating though.

[@GarageBuiltHondas]

Isn't it!? It can be so damn intimidating at first though because of it, but once you start to pay attention it all just starts to fall into place like a big ass puzzle!! Haha

[@SABRECRAFT]

i would have liked to see if there was any power difference between the pm6 and pr4

[@GarageBuiltHondas]

Pr4 fuel maps aren't meant for the sohc, so I couldn't imagine it would've been better.

[@inspyral02]

Nice series, seems like it gained a lot of drivability.

[@GarageBuiltHondas]

Thanks, and Big time!! Car feels fun now!

[@notorioussouljur]

Fun pr4 fact i got from HT a long time ago when i LS swapped my ef: The 90 PR4 (PR4-A01, A02, L01, L02) integra ECU and the 91 PR4 (PR4-A10, A60, L10, L60) is that the 90 version has an external PA sensor and the 91 version has an internal PA sensor. I forgot which year ecu i used to make my ef run better lol

+Robert Schwartz I'm not sure where to start on that, I've never experienced the issue. I would Google it, you'll probably find some forum info that may point you in the right direction. Google "crx power drain" first.

Love watching your videos bro and subscribed to your channel. From Texas Also! 1 question how you hitting those rpm's with that stock B2? I have a fresh stock reman B2 in my Ef and I'd be afraid to go past 4000 bone stock including the exhaust mani

@@GarageBuiltHondas lol true

[@M1K3YTFL]

I have a pr3 on my 91 civic and it idles at 2000 rpms then drops to around 1500 rmps. Still trying to figure out why it idles so high. Awesome channel by the way, always watching your vids.

You have a B16A correct?

[@GarageBuiltHondas]

And thanks for the kind works, it's much appreciated!

[@M1K3YTFL]

+Jon Widmer I have a d16y7 with a vtec head and the ecu came with the harness when I bought the engine.

[@GarageBuiltHondas]

Do you have any check engine lights? That ECU is the obd0 B16A Ecu. As you can see in this video, my sohc acted funky with the dohc pr4 Ecu. Yours may be doing the same because of this.

[@M1K3YTFL]

+Jon Widmer the only cel it's throwing is the knock sensor. I've read that there's a spot on the back of the block for it but I would have to look into it more.

[@kirbizle]

awesome, I've been curious about the gains made for a long time. makes me reconsider spending the time to mpfi my daily ef. one thing I'd suggest is maybe 2 1/4 exhaust, 2.5" is pretty overkill for a lower rpm non-vtec and sohc. Might hurt the low/mid rpm power.

[@GarageBuiltHondas]

90ED6LSV agreed after reading this about the exhaust, that's a good point. The 10-11 hp that came from the manifold swap made it feel like a completely different car. Are you thinking of not doing an mpfi swap now because of the minimal hp gain?

[@CatDaddyTuning]

Thanks for the end result! I happily rock DPFI with a straight/center exit 2.3" pipe off of the cat (with a muffler after the cat) and just changing the exhaust made the car feel 2x as fast but the MPFI is a real 10hp gain! On these small engine that's really huge improvement for sure.

[@CatDaddyTuning]

I actually have a video of the exhaust on my page showing how I made it

[@kirbizle]

Jon Widmer No I meant I kind of want to do it now haha. I have everything I'd need, the only other thing I'm curious about is the mpg's. If it gets worse mpg then I'd probably not do it, unless the difference is pretty minimal.

[@GarageBuiltHondas]

BattleGroundAuto I'm going to check it out in a moment, I want to see it!

[@TheMontagGarage]

Jon, I've watched this build series a plethora of times and I believe I am ready to take on the conversion myself, only problem is parts for these cars around here or the "ef" are very hard to come by(I'm the only guy in town with ef). I had one chance to meet up with some sketchy dude off our most local honda page, and the stuff he wanted to sell me weren't even for an ef... on the same note, I love watching your scrap/junkyard vid's! If I seen them cars at my junkyard I'd faint literally. Basically my question to you is would you ever be down to sell me multi point stuff for my sedan??? P.s. absolutely sick video series, they inspired me to try it on mine!

[@GarageBuiltHondas]

Absolutely, what do you need and I'll check to see what I have!

[@TheMontagGarage]

That would be awesome!! As far as parts I really haven't collected anything for the conversion, the intake manifold from the correct year, injectors and resistor box would be one of the hardest pieces to source. I am capable of doing the wiring myself just by going back and watching your video. I'd be willing to pay whatever number you have in mind!!!

[@GarageBuiltHondas]

I'll check parts Tuesday/Wednesday which are my days off this week!

[@TheMontagGarage]

Garage Built Hondas Your incredible man, I appreciate you a ton!

[@flecktards3126]

Instead of an MPFI swap, I put a Weber 32/36 on the DPFI manifold (I milled out the plenum to accommodate the airflow of a 2 barrel), used a 1984 civic distributor, and I chopped out my ECU. It blows the DPFI setup out of the water, and it is pretty competitive to the MPFI swap, even with my 4 speed.

[@GarageBuiltHondas]

Interesting, sounds like a cool mod. Whats "chopped out my ecu" mean?

[@flecktards3126]

@@GarageBuiltHondas I cut the wires to my ecu as a challenge. The car runs without and ECU so I have met my goal. Psuedo-retro EF civic was the goal. Carburated and vacuume advanced ignition.

[@ekfrank8735]

I'd like to see how much more hp your wagovan would make with an exhaust intake and retune. I miss my old ex sedan EF I got lucky and it had the MPFI from the factory. I recently put a short ram on my ek to me it feels like it made a difference in response it use to lag alot before the short ram helped it. How much did the dyno tune run you?

[@GarageBuiltHondas]

EK Frank $85 at this spot. I definitely think a short ram and better breathing exhaust will help free up some HP. I'm pretty sure I'll do a follow up once I complete the exhaust and intake. Daniel Kirby (90ED6LSV) suggested a 2.25" exhaust and I really like his advice as he knows a lot about Hondas so I'll probably shoot for that size of an exhaust instead.

[@ahmedsaadoon2455]

[@HustlePaul]

hey Jon what transmission are you running . there's a cable transmission with a shorter gear that would help. and the d16y8 intake manifold would help with power also

[@GarageBuiltHondas]

Anonymous Garage 91 CRX Si, much better than the DX that was in my wagon. I swapped it last year, my DX trans had a leak on the case somewhere and I got the transmission from a good friend and knew it was in awesome shape!

[@ProWilson21]

U need to replace that AC with a universal parallel flow condenser because R134 was design to work with parallel flow. The condenser u have will definitely give u high head pressure when it 80-100 degrees outside, and it will not get cold after 100 degrees. If u had a PFC Condenser your AC will get super cold even when its 105 degrees outside. FYI the bigger the better.

[@GarageBuiltHondas]

Do they make model special ones for this particular vehicle? No modified lines needed?

[@MooZleZ]

nice gains! it would've been interesting to see the dyno difference between the 2 ecu's tho, there must be something different about it And you want to do a short ram air intake, but if you drive in hot weather that might get you less power, since the car already dropped a bit when it was hotter with the airbox, maybe it might be a good idea to get a quality air filter for the oem airbox ? because the short ram will only be getting warm air from the engine bay, unless you build your own airbox with ducts and stuff ? I wonder what the result is going to be :D great vids bro !

[@GarageBuiltHondas]

Thanks falZ! I'm going to use the CAI that is on my track car. I ordered a larger 3" diameter short ram for the b20, and will swap the cold air to the wagon. I have the oem dust/dirt/water plastic liner around the wheels still so that will help protect the air filter. I think that will make a big difference in power. I have a K&N filter on the oem air box already, not sure if it made any difference though. I do think after an intake and exhaust I may try another crack at the Dyno to see results!!

[@MooZleZ]

That was a fun video! I'm not sure about a 2.5" exhaust though. Wouldn't that effect the scavenging too much of the post combustion?

[@GarageBuiltHondas]

Probably too large for this sohc, a 2.25 may be more suitable for this setup.

[@scorpion5975]

Hello Jon! I'm from Moldova, I have a Civic ED6 with d15b2 DPFI. I have the opportunity to put a D15Z6, will I encounter more obstacles considering it is with VTEC? Or is it better to leave the old D15b2 block with the L3 gearbox and put only the cylinder head from the d15z6 with the intake and the ECU d15z6? I'll have to pull cable for VTEC ... Thanks buddy! You're doing good videos!

[@GarageBuiltHondas]

Since they are both 1.5 litres I can't imagine it'll be a big difference in power. It'll be less work just doing the head swap. I would probably just swap the entire engine and sell the old one, no need to pull apart 2 different engines just to make one. The only obstacle will be pulling the whole engine as compared to just the head. The thing that's nice is that you'll get be able to add new parts and clean the engine bay and engine.

[@scorpion5975]

I understand that I will only gain about 20 horsepower and the VTEC system, but I would like to leave the original engine block because our law is not allowed to change the engine number, plus to this original block it feels very good. Thanks for receptivity!

+DJohn NineOneSix Since you're keeping it obd1, it'll be plug and play. No re-pinning at the shock tower. I can't remember off the top ofy head but I believe the distributor plug might be different? You'll have to look that up. Everything else will be fine.

And for the evap system I'm going to connect the little vacuum line to the hose that goes to the top of the intake manifold on the B18b1 I think the same vacuum will power the little vacuum line and open the canister evap port.

i have a 1988 wagon i need to do this conversion and also a stick conversion as well i have a 4door ef that was also auto but converted to stick can i just use same stuff to fit my wagon?

[@GarageBuiltHondas]

+Manny Del Real Yes!

[@markrent3269]

still no honda but still great, cheers

[@GarageBuiltHondas]

Hopefully you're looking? 😜

[@Benjigarage]

I just watch this whole series and my only problem is would this whole conversion work on a lx automatic or no because I really wanna do this to my car been rewatching videos but idk if I can do it with my automatic car please get back to me

[@GarageBuiltHondas]

Yes. You'll need the automatic ECU

[@jessev4303]

Hey Jon I was wondering if you could she'd come light on my problem. I bought an eg8 the engine was swapped with a D15b2 and has a MPFI swap as well. Only problem with mine is the car runs at about 1500 RPM and runs super rich. But other than that runs good. Do you have any idea what to look for on what could be the culprit? Thank you in advance. The new channel name is awesome

[@GarageBuiltHondas]

Appreciate it!! You may have a vacuum leak somewhere. Possible intake manifold, throttle body, or even TPS sensor gasket. You can spray some carb cleaner around all of those gaskets and see if it makes the engine decrease in idle at any point. If it does you may have found a leak. You can also spray soapy water on all the vacuum hoses to check for leaks, but I would just replace those. It will be about a 10 minute job and cost $5. Any check engine lights on?

[@jessev4303]

Garage Built Hondas will do that man thank you! And I have no CEL

[@DinoTheAynl]

Hey Jon, I was watching your series, and I was wondering if you have a parts list somewhere so I know what i need to do this swap?

[@GarageBuiltHondas]

Yes, it's in the very beginning of this video. No more than a minute in. kzbin.info/www/bejne/n5iqi6eedq16ias

[@curiousgeorge986]

Hey bro can you do a video on how to replace a timing belt, tensioner and oil seals. Thanks.

[@GarageBuiltHondas]

I'll have one up in about 2 months give or take.

[@carlosnavarrete3297]

hello friend greetings from mexico I have a doubt that car is the multiple of admiration? and what parts did you occupy to bring the convergence? I'm interested in doing the same to my ef

[@GarageBuiltHondas]

I'm sorry I didn't really understand the message.

[@phillipcaton6200]

I have a 90 wagon and my turn signals will not work at all fuses are good only thing I could think is the switch do you have any info on this subject

[@GarageBuiltHondas]

+Phillip Caton Yes the signal stock does go bad. You can find a brand new one for around $25 I believe.

[@nicklandry901]

hey man I’m having a fuel issue with my civic wagon that I’m doing a mini me swap on. it was originally dpfi so in addition to the vtec head swap I’m doing an obd0 to obd1 conversion with the dpfi to mpfi. I’ve got the p28 ecu, bought a jumper harness and got everything swapped and plugged in. It’ll crank and start for a second but lacks fuel and dies. the fuel pump primes when I turn on the key. just can’t figure out why the fuel pump won’t turn on with the car

[@GarageBuiltHondas]

Test the fuel pump. kzbin.info/www/bejne/n2rXaoKXpbCZnMk

[@nicklandry901]

Garage Built Hondas my fuel pump is good, I’ve got pressure, primes when I turn the car on but gets no fuel while the car is running. some have told me it may possible have to do with the ecu?

[@GarageBuiltHondas]

Yeah this car ran too, but the pump was weak and would stutter under acceleration. What's you fuel pressure coming out at?

[@nicklandry901]

Garage Built Hondas found out what my problem was. wrong banjo bolt. she’s running and driving great now

[@ratking6769]

Hey man, recently a few of my coolant lines on my dpfi decided to give out and ripped. Have been considering this mpfi swap but have an auto 90 Civic LX sedan, just wanted to know if I do decide to give this swap a shot would I need a different ecu?

[@GarageBuiltHondas]

Yes. The mpfi setup requires it.

[@ratking6769]

Oh, im sorry I didn't word myself that well lol would I need another ECU or distributor other than the pm6 or pm4, that you mentioned, considering that my car is auto?

[@GarageBuiltHondas]

Yes. Ps9

[@bassonabudget2k899]

would an exhaust and intake take it to 100+

[@ginger5.56]

Could I just a SI harness, manifold, distributor, and ecu. I not comfortable doing that much wiring.

[@GarageBuiltHondas]

Nope. Unfortunately it isn't that easy. The wiring doesn't match up to the body harness.

[@derekollberding7767]

did you have any issues upon first start up?? I did the swap to my 89 dx hatch it started like 5 times but i had to keep the gas pedal on the floor to keep it running. but now it wont start again. it just cranks and cranks

[@GarageBuiltHondas]

Only issue I had was a leaky fuel injector. You may want to check your wiring for fuel.

[@derekollberding7767]

its sparking and spitting fuel

[@GarageBuiltHondas]

Check your wiring. Sounds like something isn't correct.

[@tylerwhite1294]

so was this off of another D15 or D16? I am trying to do this to my 91 civic hatch.

[@GarageBuiltHondas]

[@benpapu4379]

I need to get another wagon ASAP :(

[@GarageBuiltHondas]

Yes you do!

[@ramones53rd3rd]

I want to do this to my wagon. How much do you think the total conversion would cost?

[@GarageBuiltHondas]

You could probably find all the parts from between $150-200. Labor might be a little pricey if you don't do it yourself though!

[@journeyquest1]

How is the D15B7 rated at 102hp stock? B2 should be 90hp.

[@GarageBuiltHondas]

+journeyquest1 You're correct, I have a d15b2 in here at 90hp. The b7 I believe is similar in build to the A6, which is probably why it has similar hp. Honestly the b2 seems similar also after getting it dyno'd with the mpfi setup. It's probably just slightly less powerful though.

[@winbarr415]

hey what's up I got 89 dx I'm looking to do the same but watching most of your dpfi to mpfi and others I'm really scared to touch anything as far as wiring but I've pretty did mostly everything to since I had it

[@GarageBuiltHondas]

It's not hard, I have 4 other videos before this one and I walk you through the entire process. It's pretty detailed to. Plus I can always offer help if you need it!

[@winbarr415]

judging from your icon pic you live in texas?

[@GarageBuiltHondas]

Winston Barr Yes, El Paso

[@winbarr415]

That's far I'm ga

[@GarageBuiltHondas]

Winston Barr Yeah, I can't just swing by and help out. lol

[@kellywesley1977]

how did you get those ecu , s to rev so high in between gears

[@GarageBuiltHondas]

Wesley Kelly what do you mean, I don't think I'm understanding. Did you mean how I redlined it? I just did a full throttle pull through the first 4 gears.

[@kellywesley1977]

Yea the red line

[@GarageBuiltHondas]

Just fast shifting, I shift hard and quick. Lol. "That's what he said!" Haha

[@yan01232]

you should do a 1/4 mile run, im very curious

[@GarageBuiltHondas]

yan01232 Probably still a 16 sec 1/4" mile.

[@rickjames203]

oh just wandering have you seen the boostedboiz channel?

[@GarageBuiltHondas]

Yes I have! They've blown up from last Sept! I started watching when they had the wagons, but looks like they have already moved on and don't touch the wagons much anymore. And the racing videos are cool, but get repetitive after a while.

[@journeyquest1]

Throw an A6 cam in there with a Y8 gear.

[@GarageBuiltHondas]

👍

[@stevetan5096]

Hi, question did you get better mpg or worse?

[@GarageBuiltHondas]

Worse

[@stevetan5096]

Thanks. Very helpful video.

[@kameronclark515]

Is there a big mileage difference?

[@GarageBuiltHondas]

Mileage?

[@kameronclark515]

@@GarageBuiltHondas gas mileage? I drive a 89 civic sedan if that helps

[@GarageBuiltHondas]

It'll go down a little.

[@erickdavidrb]

Por dicha vi todos los vídeos hasta el final. No podría invertir tanto tiempo y dinero para ganar tan solo 10 HP en comparación con el Dual Point, el D15B2 tiene 80 HP stock. Es preferible tener el motor original en óptimas condiciones, poner un buen intake de alto flujo y un buen exhaust de alto flujo, les aseguro que gana igual o más caballaje.

[@robertoalicea8891]

time to swap in a a6 cam

[@GarageBuiltHondas]

No shit, right!?!

[@williamquiala4076]

How the I make my Honda Civic 91 lx more horse power

[@GarageBuiltHondas]

kzbin.info/www/bejne/n5iqi6eedq16ias

[@sophocha]

now put a JRSC (10 psi) and some water injection :)

[@GarageBuiltHondas]

+sophocha That would be so much fun!

[@sophocha]

Garage Built Hondas I know cause I have one on a d16a8 plus water injection...turboedit for an easy map and off you go!

[@GarageBuiltHondas]

+sophocha how much HP does it make?

[@sophocha]

Garage Built Hondas not sure but it must be around 150-160hp..maybe more.

[@GarageBuiltHondas]

+sophocha that's nice, I bet that feels very stout!

[@illidanbrothers9529]

MPFI swap is always great, but 91hp is not that impressive number. What about making video series on a Z6 head swap?

[@GarageBuiltHondas]

It's better than 80, lol. I feel like the mpfi swap is just the tip of the iceberg because you have a lot of room to go forward after that. If I have an opportunity to do one I will, but nothing seems to be on the table.

[@jaygreasemonkeychung5176]

can a obd0 pm9 ecu be chipped

[@GarageBuiltHondas]

Yes, I believe so. I don't have any info on that though.

[@thebirthdaypodcast3875]

are you selling any of your cars?

[@GarageBuiltHondas]

Not yet.

[@jaygreasemonkeychung5176]

need help finding a video on chipping a obd0 pm9 ecu anyone???

[@MrWhitedizzle]

I made 115 with my dpfi. You had to have had something else wrong maybe

[@GarageBuiltHondas]

115 hp on an engine that makes 92 HP from the factory? I'd need to see the video/Dyno sheets to prove that.

[@MrWhitedizzle]

LOL MPH

[@GarageBuiltHondas]

Lmao

[@MrWhitedizzle]

But fwiw, my dpfi powered mini me (z6 head with y8 dizzy mount) is working just fine and definitely faster. Comparing the 2, the b2 dpfi makes 20 hp more than the b1 dpfi because of fuel maps and factory made throttle body spacer. With that said, i do believe it's making more than 115 HP currently

[@GarageBuiltHondas]

I was laughing when you corrected me. I was like there's no way it's making 115hp!! Haha. I like sohc engines, definitely fun to play with and you can really surprise some people!

[@TwisNinja]

pr4 ecu map is for an LS b18a by using it to run a d15 it is running too rich for the fuel map that the d15 needs, same deal goes for the b20 except it's going to run lean, both of which will cause excessive heat in cylinders and potential for detonation also higher carbon build-up, for d15b2 engine you'll need a pm5 or p04 ecu, get your HP and TQ back to the 92hp/88tq it should be there's a vid on my channel of my d15b7 with a z6 head vs a Mustang GT my vid shows how a single jingle is supposed to run here it is : kzbin.info/www/bejne/p3PQYXWdjbCaqKs

[@GarageBuiltHondas]

+John Cook Yes, I was just using the PR4 as a temp fix until you can find the PM6. The PM5 will not work as it's the DPFI ecu and see converting to MPFI only.allows use of an ECU with 4 injectors. The best ecu to run on this setup I have (d15b2 engine with MPFI parts) would be the P06 from the 92-95 Civics (DX,LX,CX) and converting to obd1 since that is the 1.5L engine with MPFI. I believe that would give you the best gas mileage and power for the setup. I've always felt the MPFI PM6 combo on a 1.5L runs rich and burns more fuel than needed but it's still safe.

[@kcustomz8438]

Can you sell me a mpfi kit for my 89 civic dx hatch

[@GarageBuiltHondas]

Do you need everything? It might be easier to piece it together.

[@kcustomz8438]

Garage Built Hondas yes I do but I have a 98 f20b complete engine from Aln Jdm that I want to drop in

[@GarageBuiltHondas]

It should come with the intake manifold and parts already.
